MACHINE FOR BEVELING THE EDGES OF MOUNTS AND PRINTS.

Specification of Letters Patent. Patented June 22, 1 920,

Application filed July 2, 1919. Serial No. 308,291.

To all whom it may concern:

Be it known that I, ALLEN P. Home), a citizen of the United States, residing at Taunton, in the county of Bristol and State of Massachusetts, have invented new and useful Improvements in Machines for Beveling the Edges of Mounts and Prints, of

which the following is a specification.

This invention relates to certain new and useful improvements in a machine for bevel;

ing the edges of mounts and prints, known in the art of bookbinding as insert mountcut a neat miter joint at the corner or inter section of adjacent beveled edges.

The invention further resides in the fea turesof construction and the arrangements and combinations of parts hereinafter described and claimed, reference being had to the accompanying drawing wherein:

Figure 1 is an elevation of the improved machine;

Fig. 2 is a detailed elevation of the presser head in one position; and v Fig. 3 is a similar view thereof in its other position; e I Fig. 4 is a vertical section through the presser head; I

Fig. 5 is a section through a print having its edges beveled and g s Fig. 6 is a similar view of a mount having the edges of the print-receiving opening beveled and Fig. 7 stick.

In the assembled showing of Fig. 1 a frame 1 is shown having spaced tracks 2 which are traversed by a wheeled carriage 3 the same being so mounted to support and carry the work over a revolving emery wheel 4:, journaled in a bracket 5 that is offset from the frame.

Pivoted on a standard 6 is a vertically swinging arm 7 journaled between its ends is a perspective View of the presser to have one end overhang the emery or abrading element 4 and its opposite end arranged to engage a limitation stop 8 embodying the adjustable stop screw 9 for defining the vertical movement of the opposite orfree end of the, arm. The arm is swung by means of the compound levers 10 gdapted to be operated by the operators oot. I I

The presser head comprises a more or less keystone shaped plate or block 11 pivoted to the free end of the, arm 7 by a bolt 12 and limited in its pivotedmovement by reason of-the adjusting bolt 13 engaging in' the arcuate slot 14 in the upper part of the block. Integral with the block or plate 11 is avertical bearing sleeve 15 in which is rotatably secured aholder or carrier 16, said carrier having an upper fixed flange 17 and a removable keeper flange 18 in screw threaded engagement with carrier 16 for engaging the opposite ends of the sleeve bearing. The removable keeper is formed with diametrically opposite perforated ears 19- adapted to I'BCQIVQyWllGH in underlying relation, a vertically slidable lock pin 20 carried by the sleeve 'bearingand guided in its vertical movement by an outstanding perforated ear 21. A button or knob 22 on the pin facilitates the manipulation thereof.

Axially extending through the holder 16 is the presser stick 23 that is retained therein by a set screw 24 and has'its opposite longitudinal edges beve'led in opposite di rections for obtaining the proper miter at the junctions of the beveled edges. Thisv stick can be considered the presser foot and the carrier 16 the presser head, thestick being designed to bring the mount 25 or the print 26 down onto the rotating emery wheel as the work carriage movestherebeneath. V i I In operation, the operator places, av mount on the carriage so that the edge of the opening cut therein lies over the. wheel, and the marginal portion of the mount extends beyond'the wheel and off from the carriage. In the case of a print, the bordering edges are placed above the wheel. now depresses the foot lever to bring the presser foot down onto the mount or print and the latter down into engagement with the rotating emery wheel. The carriage is then moved along its tracks while the operator'holds the work on the carriage with The operator i his hands. W hen one edge is beveled the work is turned to present another edge and so on until the surrounding edges have all been beveled.

The beveled faces of the presser stick cause only the directly underlying part of the work to be acted on by the wheel and therefore when the carriage is stopped the end of the cut will be on a bias for effecting a neat joint with the adjacent edge. The holder is capable of being rotated a half turn so as to reverse the presser stick for mounts having wide margins and also for the purpose of acting on the work without having to reverse the same. The weight of the presser carrying arm. is suflicient to elimiate all chattering thereof and thus the moving of the work beneath the presser foot 23 will result in a clean and even beveled cut. The presser head 16 is angularly adjustable for setting the presser foot properly on the work to secure the best results in which position it is locked by the screw bolt 18.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is-- 1. In a bevel cutting machine, a frame, a carriage movable thereon, an emerywheel adjacent the path of travel of the carriage, an arm pivoted between its ends to the frame, a presser head carried by one end of the arm, a stop engaging the opposite end of the arm to limit downward movement of the presser head and means to actuate the arm.

2. A bevel cutting machine comprising a frame, a carriage movable thereover, an emery wheel arranged adjacent the path of movement of the carriage, an arm ivoted for limited vertical swinging, a heat block pivoted on the end of the arm over-lying the wheel, said block formed with a vertical sleeve bearing and an arcuate slot, a bolt passing through the slot for adjustably securing the block to the arm, a holder jour naled in the sleevc bearing and provided with spaced perforated ears, a vertically slidable lock pin on the sleeve bearing for engaging in either ear, and a presser stick secured in the holder and having both of its longitudinal sides beveled.

3. A bevel cutting machine comprising a rotary cutter, a movable support arranged adjacent the same, and a presser foot arranged above the cutter for movement toward and from the same to move the work on the support against the cutter, said presser foot having its sides oppositely bev eled.

4. A bevel cutting machine comprising a cutter, a work support movable alongside the same, a vertlcally movable and horizontally rotatable head above the cutter,

means for securing angular adjustment of the head, and a presser foot carried by the head.

5. A bevel cutting machine comprising a cutter, a work support movable adjacent the same, a head angularly adjustable above the cutter, a reversible holder carried by the head, and a presser stick carried by the holder.

6. A bevel cutting machine comprising a cutter, a work support movable alongside the cutter, a head arranged above the cutter and provided with a vertical sleeve bearing, a holder rotatable in the bearing and formed with a peripheral flange engaging one end of the bearing, a removableke'eper flange secured to the holder for engaging the oppositc end of the bearing and formed with spaced perforated ears, a locking device on the bearing for engaging in a selected one of the ears to secure the holder in a set position, and a presser member carried by the holder.

7 In a bevel cutting machine, a cutter, a work support movable therealong, a horizontally rotatable head above the cutter, means to support the head, means to allow of vertical angular adjustments of the head,

and a presser foot vertically adjustable in the head.

8. In a bevel cutting machine, a cutter, a work support movable therealong, a horizontally rotatable head above the cutter, means to support the head, means to allow of verticalangular adj ustmentsof the head, a presser foot carried by the head, and means to allow of vertical adjustments of the presser foot.

9. In a bevel cutting machine, a cutter, a mat carrieradj acent the cutter and means to bear on the mat to hold same against the cutter, said means being beveled to act as a guide in the formation of corner miters.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ALLEN P. HOARD.
